Expert Electricians & Electrical Services in Troy, MI
Interested in making some electrical changes to your home? Randazzo has an experienced electrical team, led by our knowledgeable master electrician. We also act as an emergency electrician serving Troy, MI residents, and can help you stay prepared for tough situations like power outages by installing standby generators.
Backup Generators
Michigan ranks third on the list of states with the most power outages in the country. In places like Troy, we can partly put this down to the aging electrical infrastructure in Oakland County. In older parts of Troy, like some of the neighborhoods around Big Beaver Road, for instance, many of the houses generally just have older electrical systems in place.
Because of this, we can’t recommend whole-home generators enough for any residents living in Troy — we’re able to install, provide maintenance, and repair these standby generators quickly, so don’t hesitate to get in touch if you’re sick of being in the dark during another power outage.
Circuit and Panel Upgrades
Many of the houses built in Troy, particularly some of the ones around Wattles Road, were built prior to 1995. While this definitely gives them a charm that you don’t see among some of the more modern houses in the city, it likely means that they have electrical panels that aren’t capable of handling many of the utilities and appliances that we use today.
So, if you’ve just had new appliances delivered and need more power, our team has the ability to install circuit and panel upgrades or repair existing units that need work — whether you’re looking at inconsistent power supplies or you’re beginning to notice burn marks around your panels.
Maintenance and Inspections
Still, even after installing new electrical systems — from lighting to standby generators — we’re more than aware of the importance of regular maintenance and electrical inspections to ensure that all of the electrical systems in your home are safe and don’t have any electrical code violations.
Our team of expert electricians is certified and up to date with the advanced training needed to keep your home safe from any fires, shocks, or other kinds of damage — whether that’s by correcting the cables, conductors, and wires being used or ensuring proper wiring for your specialty electrical systems.
